Okay thank you both for the feedback. I have gone through the initialization that is in the Adafruit libraries for the Blacktab parameter. I don't know whether this is the right option but again the documentation is poor for the libraries so I didn't know which to use so I went with the simplest.
This is my initialization followed by my write to the memory:
//Display initialization
void init_display(void){
uint8_t command[1]; //Initialize send buffer
uint8_t data[6]; //Initialize send buffer
// 1: Software reset, 0 args, w/150 ms delay
command[0] = ST7735_SWRESET;
TFT_Write(command, 1, CMD);
delay(150);
// 2: Out of sleep mode, 0 args, w/500 ms delay
command[0] = ST7735_SLPOUT;
TFT_Write(command, 1, CMD);
delay(500);
// 3: Frame rate ctrl - normal mode, 3 args: Rate = fosc/(1x2+40) * (LINE+2C+2D)
command[0] = ST7735_FRMCTR1;
data[0] = 0x01;
data[1] = 0x2C;
data[2] = 0x2D;
TFT_Write(command, 1, CMD);
TFT_Write(data, 3, DATA);
// 4: Frame rate control - idle mode, 3 args: Rate = fosc/(1x2+40) * (LINE+2C+2D)
command[0] = ST7735_FRMCTR2;
data[0] = 0x01;
data[1] = 0x2C;
data[2] = 0x2D;
TFT_Write(command, 1, CMD);
TFT_Write(data, 3, DATA);
// 5: Frame rate ctrl - partial mode, 6 args: Dot inversion mode, Line inversion mode
command[0] = ST7735_FRMCTR3;
data[0] = 0x01;
data[1] = 0x2C;
data[2] = 0x2D;
data[3] = 0x01;
data[4] = 0x2C;
data[5] = 0x2D;
TFT_Write(command, 1, CMD);
TFT_Write(data, 6, DATA);
// 6: Display inversion ctrl, 1 arg, no delay: No inversion
command[0] = ST7735_INVCTR;
data[0] = 0x07;

TFT_Write(command, 1, CMD);
TFT_Write(data, 1, DATA);
// 9: Power control, 2 args, no delay: Opamp current small, Boost frequency
command[0] = ST7735_PWCTR3;
data[0] = 0x0A;
data[1] = 0x00;
TFT_Write(command, 1, CMD);
TFT_Write(data, 2, DATA);

}
